64 CHAPTER 4: WORKING WITH NETWORK PLANSTraffic Ports Used bya Mobility DomainWhen deploying a Mobility Domain, you might attach the WX switches tosubnets that have firewalls or access controls between them. Within aMobility Domain, the WX switches exchange information and other typesof traffic, depending on your configuration of AAA and variousmanagement services.Table 10 provides a summary of the traffic ports typically used by aMobility Domain and its associated AAA and management functions.The traffic typically sent between WX switches within a Mobility Domainuses IP/UDP protocol 17 traffic on port 8817 for both source anddestination. Roaming traffic uses IP protocol 4.Creating a MobilityDomainThe Create Mobility Domain wizard requires you to select the switches toplace in the Mobility Domain and to select the seed switch. Add theswitches to the network plan before you configure the Mobility Domain.1 Select the Configuration tool bar option.2 Select the network plan in the Organizer panel.3 Select the Mobility Domain task in the Task List panel. The CreateMobility Domain wizard appears.4 In the Name box, type the name for the Mobility Domain (1 to 16characters, with no spaces or tabs).5 Click Next.Table 10 Traffic Ports Used for AAA Servers and Management ServersProtocol Port FunctionIP/UDP (17) 1812 RADIUS authentication (default setting)IP/UDP (17) 1813 RADIUS accounting (default setting)IP/TCP (6) 443 Secure Sockets Layer protocol (SSL)management using Web ManagementIP/TCP (6) 8889 SSL management using 3WXMIP/TCP (6) 23 Telnet managementIP/UDP (17) 161 SNMP get and set operationsIP/UDP (17) 162 SNMP trapsIP/ICMP (1) N/A Several types (for example, ping)IP/UDP (17) 123 Network Time Protocol (NTP)IP/UDP (17) 53 Domain Name Service (DNS)
